CHARLES W. LAWVRENCE, OF NEW YORK, N. Y.

CURTAIN-POLE RING.

SPECIFICATION forming part of Letters Patent No. 400,348, dated March26, 1889.

Application filed November 8, 1888. Serial No. 290,311. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. LAWRENCE, of the city, county, and Stateof New York, have invented certain new and useful Improvements inCurtain-Pole Rings, of which the following'is a specification.

This invention relates to an improved curtain-pole ring of that class inwhich the antifriction rollers are used at the upper part of the ringfor facilitating the movement of the same over the curtain-pole and theinvention consists of a curtain-pole ring provided with a centralannular bead, a wire located in said head at the upper part of the ring,and antifriction balls or rollers, Which are pivoted to said wire andlocated in openings at the upper part of the ring.

In the accompanying drawings, Figure 1 represents a side elevation,partly in section, of my improved curtain-pole ring. Fig. 2 is a topView of the same; and Fig. 3, a vertical transverse section of the sameon line as 9:, Fig. 1.

Similar letters of reference indicate corresponding parts.

A in the drawings represents a curtain-pole ring formed of a fiatconcave body, which is provided with a central annular bead, a. In thebead a is located and soldered or otherwise attached a wire, I), whichextends along the upper inner part of the ring, and which serves asapivot for a number of spherical anti-friction balls or rollers, B, thatproject through apertures of the ring A above and below the same, theinner parts of the balls or rollers B resting on the curtain-pole andfacilitating the motion of the same over the curtain-pole, as thefriction. of the ring with the curtain-pole is considerably reduced.

In making the ring the spherical rollers are strung up on the wire andthe balls placed in position in the openings of the ring, aft-er whichthe ends of the pivot-wire are secured into the bead of the ring. Asimple and effective construction of an anti-friction curtain-pole ringis thus obtained, which is applicable to the cheapest kinds of rings,which heretofore could not be furnished with antifriction devices, owingto the expense of the same. The exterior bead of the ring also improvesconsiderably the appearance of the ring. The rollers can easily beassembled on the wire and the latter then placed into the hollow beadand secured to the ring, thus greatly facilitating the applying of therollers on the ring.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A curtain-pole ring provided with a central annularbead and a pivot-wire secured into said bead, and with anti-frictionrollers applied to said wire and located in openings of thecurtain-ring, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing Witnesses.
